摘要
基于北京市中心城区的核心区1 km^(2)试验区范围内的空间资源,完成多维多角度数据摸底,为搭建核心区空间二三维一体化展示平台提供数据基础,并研究如何应用二三维地理信息系统(Geographic Information System,GIS)技术,整合核心区全息三维模型数据和各类专题数据,搭建地上地下、室内室外、二三维一体化的二三维展示应用系统,为核心区精细化管理提供有力支撑,也为北京市未来数字孪生城市的建设积累初步经验。
Based on the spatial resources within a square kilometer test area in the core area of the central city in Beijing,the multi-dimensional and multi-angle mapping was completed,which provided data basis for the construction of the spatial two-dimensional and three-dimensional integrated display platform in the core area,and this paper studiedhow to apply the two-dimensional and three-dimensional Geographic Information System technology to integrate the holographic three-dimensional model data and various thematic data of the Beijing core area,and build the two-dimensional and three-dimensional display application system of ground and underground,indoor and outdoor,and two-dimensional and three-dimensional integration,which provided strong support for the fine management of the core area.It accumulated preliminary experience for the construction of digital-twin city in Beijing in the future.
